It is natural selection, as basically the environment causes a selection for those who have better adaptations to survive
B. Consumers produce Co2 for which plants need to allow photosynthesis to turn back into oxygen.
Answer:
See the second attached image showing the gametes from the parent with the location of the centromere indicating the type of chromosome
Explanation:
According to the position of the centromere, chromosomes can be of 4 types namely:
- Metacentric
- Acrocentric
- Telocentric
- Sub-metacentric
A metacentric chromosome is a chromosome that has no short or long arm. The arms are equal in length with the centromere joining the two sister chromatids located at the center.
Acrocentric chromosomes have unequal arm lengths with the centromere skewed towards one end of the chromosome.
Telocentric chromosomes have their centromeres at one end of the chromosome.
Sub-metacentric chromosomes have unequal arm lengths but the centromere is not as skewed to one end of the chromosome length as found in acrocentric chromosome.
The only possible gamete from <em>aa bb</em> parent is <em>ab</em>. Recall that the allele <em>a </em>is located on a metacentric chromosome while allele <em>b </em>is located on acrocentric chromosome.
Huddling is the correct awnser
Answer:
Alpha decay or α-decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus) and thereby transforms or 'decays' into a different atomic nucleus, with a mass number that is reduced by four and an atomic number that is reduced by two.
